Great, here’s how to remove it from your commits:
Run git commit --amend
Your text editor will open. Delete the line: Co-authored-by: Github Copilot <[email protected]>
Save and exit
Force push the change: git push --force-with-lease
Or people could instead not use Microslop software, easy fix for the AI bullshit. But yeah of course you're technically right.
The original commit is (publicly) preserved on Github.com until perpetuity, so I wouldn't use the term 'remove'.
